Hi all, There is an obvious strip in some of my MNF eigenimages. It looks odd. So I double-checked my original AVIRIS image and did find some bands which have strip in the center. However, after I removed those "bad" bands from original image and redid MNF transform, there still is a stip in the center of image. I don't know why. Does it mean there are still some noisy bands in my data? If so, how can I find those bands? Thanks very much, Lin
